In brief
Choose aluminum for a modern look, the widest range of slat, louver and privacy options, matching gates, and noncombustible material (based on the manufacturer’s fire test documentation). Choose composite (WPC) for the warm look of wood without staining or sealing. Both are low maintenance, and many homes use both: aluminum at the front, composite in the backyard.
Aluminum and composite are the two fence materials homeowners ask us about most once they have ruled out wood and vinyl. We sell both at our Panorama City showroom, so we have no reason to push one over the other. This guide compares them honestly on looks, privacy, upkeep, California sun, fire, cost and installation, and ends with a simple way to decide.
What is an aluminum fence?
An aluminum fence is built from extruded aluminum slats, rails and posts with a powder-coated finish. Our systems use T6063 aluminum and come in five series, from slim 2 inch slats to wide 6 inch planks and angled louvers, each with matching pedestrian, sliding and double swing gates. See them side by side in our aluminum fence series comparison.
What is a composite (WPC) fence?
Composite fencing, often called WPC (wood-plastic composite), blends wood fibre with polymer into planks that look like timber. Our WPC fence panels are UV-stabilized and moisture-resistant, and they need no staining, oiling or sealing. They mount on an aluminum-framed structure with matching WPC gates and end post kits.

Looks: modern lines or warm wood
This is usually the deciding factor. Aluminum reads as clean and architectural: horizontal slats, crisp louvers, matte black or white. Composite reads as natural and warm, closer to a stained cedar fence.
If you love the wood look but want aluminum’s other strengths, there is a middle option. Our Linea Series is a wood-look aluminum fence with 4 inch overlap slats, so you get the timber tone on an aluminum system with matching gates.
Privacy
Both materials can give you a fully private fence. Composite planks are usually solid. Aluminum gives you more control: full-privacy overlap slats, privacy panels with no gap, semi-privacy panels with a small gap for light and air, and Ventura louvers that block the direct line of sight while letting a breeze through. Read more in our guide to aluminum privacy fence.
Maintenance
Both are a big step up from wood. Neither needs painting, staining or sealing. A rinse with a hose and mild soap a few times a year keeps either looking good. The practical difference is in repairs: aluminum panels and slats can be replaced individually, so check how composite panels are replaced before you buy.
California sun, heat and coastal air
Southern California is hard on fences: strong UV, hot dry summers and salty air near the coast. Powder-coated aluminum resists UV fading and weathering and does not rust like steel. Our WPC panels are UV-stabilized and moisture-resistant. Whichever you choose, ask how the finish is applied and what the warranty covers for sun and fading.
Fire-prone areas
If your home is in or near a high fire hazard area, material matters. Lumina aluminum fence systems are noncombustible, based on the manufacturer’s fire test documentation. Composite contains wood fibre and polymer, so it is not a noncombustible material. California is also adopting new rules for the area right around homes, so check your city’s current requirements. Our Zone 0 fence guide explains what is known so far.
Colors and finishes
Aluminum is powder coated, so the color is part of a baked-on finish rather than paint that peels. Matte black and white are the most popular choices for modern homes, and series such as Ventura are available in the full RAL color range, which helps if you want to match window frames, trim or a gate you already have. Wood-look aluminum, like our Linea Series, adds a timber tone on an aluminum system.
Composite comes in timber-inspired tones and plank textures. Our WPC range includes woodgrain and dark gray options. If you want a fence that disappears into a garden, a natural composite tone can be the softer choice; if you want the fence to frame a modern facade, aluminum gives you crisper lines and more color control.
Gates and driveways
Gates are where the two materials differ most. Every Lumina aluminum series has matching pedestrian, sliding and double swing gates in the same profile and finish, with matching hinges, latches and handles included. Sliding and swing gates are automation-ready and work with leading gate motors, so a driveway gate can match the fence exactly. Browse our aluminum gates.
Composite fences usually pair with pedestrian gates. For a wide driveway or an automated entrance, most homeowners choose an aluminum gate, even when the rest of the fence is composite.
Pools, slopes and hillside lots
Around a pool, the fence has to meet your city’s pool barrier rules for height, gaps and self-closing gates. Aluminum pool fence panels with matching pool gates and surface-mount posts for concrete decks are a common choice; see our aluminum pool fence guide and confirm the requirements with your city before you order.
On slopes and hillside lots, panels are usually stepped down the grade, and aluminum is easy to cut to fit. Several of our series can be cut down to any size, which helps on uneven runs. Send photos of the whole run, including the slope, when you request a quote.
Cost: what to compare
Prices depend on length, height, privacy level, gates, posts, site conditions and installation, so compare complete quotes rather than panel prices. Full-privacy profiles in either material use more material than open ones. Gates add frames, hardware and posts, and automated gates add more. Our aluminum fence cost guide walks through every factor and how to plan for it.
Also compare what you will spend later. Both materials avoid the repainting and re-staining that wood needs, and aluminum is backed by our 25-year limited warranty.
Installation
Both materials install on posts, and our WPC panels mount on an aluminum-framed structure. Slopes, hard ground, concrete and old-fence removal affect the job more than the material does. We install through our licensed installation partners, and one quote covers materials and installation. See fence installation in Los Angeles.
Which should you choose?
Choose aluminum if
- You want a modern look with slats, louvers or overlap profiles
- You need matching driveway, sliding or pedestrian gates, or plan to automate a gate
- Your home is in a fire-prone area
- You want semi-privacy or airflow options, not only a solid wall
- You want to match the fence to a specific color
Choose composite if
- You want the warm look of wood without staining or sealing
- The fence is a backyard or garden run where a solid plank look fits best
- Your home and landscape lean natural or traditional
Use both if
You want aluminum at the street, with gates, and composite in the backyard. Planning both together keeps heights, colors and posts consistent.
Common mistakes to avoid
- Choosing from a photo alone. Slat width, gap and wood tone look different in person.
- Forgetting the gates. Decide on gate type and count before you choose a material.
- Skipping local rules. Front-yard height limits, pool barrier rules and HOA guidelines vary by city.
- Comparing panel prices only. Posts, gates, slopes and installation change the total more than the panel does.
- Ignoring fire risk. In fire-prone areas, the material next to your home matters.

Aluminum vs Composite Fence Questions
What are the downsides of composite fencing?
Composite (WPC) is made from wood fibre and polymer, so it is not a noncombustible material, which matters if you live in a fire-prone area. It also comes in a narrower range of looks than aluminum, mostly timber-inspired tones and plank profiles. For a modern slat or louver look, aluminum gives you more choice.
What are the downsides of aluminum fences?
Aluminum does not look like real wood unless you choose a wood-look finish, and full-privacy profiles use more material than open ones, so they cost more. Like any dark surface, a black fence also warms up in direct summer sun.
Which is better, composite or aluminum?
Neither is better for every yard. Aluminum suits modern homes, gates, fire-prone areas and anyone who wants many slat, louver and privacy options. Composite suits homeowners who want the warm look of wood without staining or sealing. Many properties use both.
Is composite more private than aluminum?
Not necessarily. A solid composite plank fence is fully private, but so are aluminum privacy profiles with no gap, such as overlap slats or privacy panels. Aluminum also offers semi-private and louvered options that composite usually does not.
Can I combine aluminum and composite fencing?
Yes. A common approach is composite panels for a backyard run and aluminum for the front fence and gates. Planning both together keeps the colors, heights and posts consistent.
How long does an aluminum fence last?
Our aluminum fence systems are T6063 aluminum with a powder-coated finish and are backed by a 25-year limited warranty. Ask about the warranty on any composite product you are considering, since terms vary by product.
Do you install aluminum and composite fences?
Yes, we do. We install through our licensed installation partners.
